What is Gamma Exposure (GEX)?
Gamma Exposure represents the sensitivity of an option's delta to changes in the underlying price. Market makers hedge their gamma exposure, creating support/resistance at high GEX strikes.
Key Levels:
- Call Wall: Strike with highest positive GEX (resistance)
- Put Wall: Strike with the largest put GEX, shown as the deepest negative bar (support)
- Gamma Flip: Where total GEX changes from negative to positive
Positive GEX: Market makers sell into rallies, buy into dips (stabilizing).
Negative GEX: Market makers buy into rallies, sell into dips (amplifying moves).

Understanding MARA gamma exposure
MARA is the largest publicly traded Bitcoin miner by hash rate, and mining equities behave like leveraged calls on the coin: revenue scales with Bitcoin's price while costs are largely fixed, so a 10% move in BTC routinely produces a much larger move in MARA. Its gamma exposure reflects that leverage, with implied volatility persistently among the highest in liquid US equities and open interest heavily concentrated in short-dated calls.
The low nominal share price and dollar strike spacing pack MARA's gamma tightly around spot, so its call wall and put wall are constantly in play rather than distant reference points. Miners also carry an idiosyncratic risk that pure crypto proxies do not - network difficulty adjustments, energy costs, and the periodic halving all compress margins independent of price - which means MARA's gamma regime can deteriorate even while Bitcoin holds up. Read the flip level as a crypto-leverage gauge: below it, MARA's amplified moves get amplified again by hedging.

MARA GEX methodology and limitations
QuantWheel calculates MARA GEX from the selected expirations, available options data and the formula displayed in the calculator. The result summarizes modeled gamma exposure by strike.
GEX is a model output, not observed dealer inventory or a price forecast. Open interest does not identify who owns an option, and the displayed call wall, put wall and gamma flip can change when the inputs or selected expirations change.
MARA GEX FAQ
What is MARA GEX?
MARA GEX estimates gamma exposure across listed MARA options using option gamma and open interest. It helps you compare how modeled exposure is distributed by strike and expiration. MARA GEX does not reveal actual dealer positions or predict where MARA will trade.
How do I read the MARA call wall and put wall?
QuantWheel labels the MARA call wall as the strike with the largest positive modeled GEX and the MARA put wall as the strike with the largest negative modeled GEX in your selected data. Compare both with the MARA price and expiration choices. They are reference levels, not guaranteed support or resistance.
What is the MARA gamma flip?
The MARA gamma flip is the price where modeled net gamma crosses zero for the selected MARA options data. Compare it with the current price and the shape of the strike chart. The MARA gamma flip is a model output, not a trading signal.
Which expirations should I use for MARA GEX?
Start with the nearest MARA expiration to study short-dated positioning, then add later expirations to compare a broader part of the options chain. Each selection changes which MARA contracts are included, so compare one expiration with a combined view before drawing conclusions.
Is the MARA GEX calculator free?
Yes. You can run up to three free MARA GEX calculations per day on the public tool. After using those calculations, continue for free in the GEX Sandbox. Check the current QuantWheel pricing page for plan access details.
